| 目的 研究铝合金轮毂旋压成形工艺参数对成形质量的影响。方法 运用有限元软件建立数值模型； 以减薄率、 摩擦因数、 旋轮圆角半径、 进给比和芯模转速为自变量， 以内径偏差和壁厚偏差为目标函数， 建立四因素四水平正交试验。结果 极差分析得到第一道次强力旋压对壁厚偏差的影响主次关系为： 旋轮圆弧半径ρ>进给比f>摩擦因数μ>芯模转速nM， 对内径偏差的影响主次关系为： 旋轮圆弧半径ρ>进给比 f>芯模转速 nM>摩擦因数μ。结论 通过有限元分析得到了旋压工艺参数对轮毂内径与壁厚偏差的影响规律， 为实际生产中工艺参数的选择提供了指导作用。 |

| In order to study the influence of process parameters on alloy wheels spinning forming quality， finite element software was used to establish a numerical model；Thinning rate，friction coefficient，spin the wheel radius， feed ratio and mandrel speed as the independent variable， internal diameter and wall thickness deviation as the objective function， establish four factors and four levels orthogonal experiment. Range analysis to get the first pass，second pass power spinning wall thickness deviation affection of primary and secondary relationship: Spin the wheel radius ρ> feed ratio f> friction coefficient ρ> mandrel speed nM， The impact on the internal diameter deviation of the primary and secondary relationship： Spin the wheel radius ρ> feed ratio f> mandrel speed nM> friction coefficientμ. Obtained the spinning process parameters influence on the inner diameter and the wall thickness deviation of the wheel by finite element analysis，Providing guidance for the selection of process parameters in the actual production. |
